Pensoft at TDWG2026: Pushing the boundaries of innovation in biodiversity data management forward

Last week marked another annual meeting of the Biodiversity Information Standards network, otherwise known as TDWG, with the Norwegian capital Oslo hosting the event between 20 and 25 September.

TDWG is the international, non-profit organisation formerly known as the Taxonomic Databases Working Group, which develops and maintains the standards, such as Darwin Core, that allow biodiversity data to be shared, integrated and understood across institutions worldwide.

The six-day programme was a meeting point for over 300 stakeholders from research, practitioner and corporate circles, with proceedings centred around one central topic – “Research and Robot- Ready Biodiversity Data Standards”. In that sense, the themes of accessibility, responsibility, innovation and collaboration were foremost on the minds of participants as they contemplated how information on the biosphere should be extracted, consolidated and shared in the years to come.

As a long-standing partner of TDWG, Pensoft Publishers served as both a sponsor and an exhibitor for the event. In the latter capacity, the company contributed with a joint booth for three of the EU-funded projects it is leading the outreach efforts for:

BMD – an initiative working towards a Biodiversity Explorer for high-throughput biodiversity monitoring tools, biodiversity data and biodiversity analyses for better conservation across Europe
TETTRIX – a new arrival building a next-generation taxonomic system connecting knowledge, expertise and innovation for all across the Old Continent
ANERIS – a pan-European effort to mobilise a network of operational marine biology via a new technological infrastructure

A number of other projects from Pensoft’s communication portfolio also found a place in the display, including BEAGLE, OneSTOP, B-Cubed, MAMBO, OBSGESSION and BioAgora. Furthermore, 14 of the company’s journals were in the spotlight, including Biodiversity Information Science and Standards (BISS), the official journal of the TDWG community (where all of the conference’s abstracts are set to be published).

Crucially, the event also saw the official launch of ORPHO, Pensoft’s new collaborative workspace for scientific writing. Founder and CEO Prof. Lyubomir Penev and CTO Teodor Georgiev conducted live demos of the tool, showcasing how manuscripts crafted within it with full version control for authors become discoverable, interoperable and FAIR-compliant.

In the context of TDWG2026’s agenda, they also presented ORPHO’s integrated semantic annotation and communication instruments as part of the workshop “How Literature Services can Support & Benefit from Biodiversity Publication and Data Standards?” on 24 September. The workspace was received with anticipation and enthusiasm by attendees, with many expressing a desire to test it out for themselves.

They were also treated with a tease of Pensoft’s next large-scale endeavour, as Senior Communications Officer Peter Bozakov pulled the curtain behind the forthcoming communication platform for research projects Scientiana.

As for other notable contributions to the wider conference agenda by researchers affiliated with Pensoft’s publishing or project activities:

The session “Operationalising Biodiversity Digital Twins within Data Space Ecosystems”, which was co-led by BMD coordinator and long-time author and reviewer across several Pensoft journals, including Biodiversity Data Journal and Research Ideas and Outcomes, Niels Raes, and showcased a number of innovative outputs from the project. As such, it was an important occasion to assess the initiative’s progress towards unifying Europe’s Data Space within a single Biodiversity Explorer.

The symposium “Publishing and Communications Promoting Biodiversity, Natural History Collections, People, Data and Data Standards”, for which Deborah Paul (co-Editor-in-Chief of the National History Collections and Museomics (NHCM) journal) had the role of co-organiser. Within it, the TETTRIX project’s vision for the automated tracking of taxonomic research activities was laid out by consortium member David Fichtmüller. Moreover, Shelley James (co-Editor-in-Chief for NHCM) delivered an insightful talk on the creative promotion of biodiversity data and standards for success and recognition.

Notably, the Biodiversity Information Science and Standards (BISS) journal is the home for TDWG conference abstracts. TDWG 2026 presenters can currently submit their abstracts there and publish them in an extended abstract or mini-paper format completely free of charge. The journal also hosts abstracts from conferences held over the past decade. You can browse the TDWG 2026 collection here.

Last but not least, the company’s sponsorship supported two awards at TDWG2026 (with a free publication in a Pensoft journal as an accompanying prize):

Best Student Oral Presentation – awarded to Yeshan Qui for “Reporting structure and sampling-bias correction in citizen-science bird data across Asian cities”
Best Student Poster – awarded to Claudia Campanini for “Improving marine fieldwork documentation and metadata with Adaptable Standardised Methods Reporting (ASMR)”

Overall, TDWG2026 proved itself a crucial forum for mapping out the future of biodiversity monitoring and the management of the myriad data streams that emerge from it. Pensoft is proud to be an important actor in this process, contributing with innovative tools and solutions at the heart of the interface between research and practice. As summarised by Prof. Penev:

“Given its status as a large-scale conference centred around the future of biodiversity sciences in the age of AI, TDWG2026 was a crucial venue for unveiling Pensoft’s forward-looking vision for academic publishing and science communication. The “pearl” of these pursuits is undoubtedly the ORPHO workspace, a tool that is well-placed to introduce a new standard when it comes to collaborative AI-FAIR research in Europe and beyond.”

New click beetle species named after Dominican Republic’s Indigenous Arawak people

Lissomus arawak measures under a centimetre long and is easily recognised by its shining and almost hairless black body, alongside its pale-yellow antennae segments.

A new species of click beetle with a glossy and highly domed black body has been described from cloud forest sites in the mountains of the Dominican Republic, and named in honour of the Arawak peoples who lived on the island before European colonisation.

Lissomus arawak measures under a centimetre long and is easily recognised by its shining and almost hairless black body, alongside its pale-yellow antennae segments. It is only the third species of the genus Lissomus known from Hispaniola, and the third recorded anywhere in the Greater Antilles.

Lissomus arawak, lateral habitus. Image by J. Pirkl, 2025, used with permission.

The study, published in the open-access journal Alpine Entomology, was carried out by Paul J. Johnson of South Dakota State University and Jiri Hodecek of the Swiss Human Institute of Forensic Taphonomy, as part of an ongoing survey of Dominican insect life. Specimens were found at three sites in montane broadleaf and cloud forest between roughly 600 and 700 metres, near the Sierra de Bahoruco and in the Cordillera Septentrional.

Rather than resembling the two other Lissomus species already known from Hispaniola, the new beetle turned out to be structurally closer to species from Central and northern South America.

“The morphological differences suggest that the Lissomus species of Hispaniola may not all descend from a single colonisation event.

One possible explanation is therefore that ancestors of these beetles reached the Greater Antilles on at least two separate occasions. This remains a testable hypothesis rather than a demonstrated evolutionary history.”
The Research Team

The species is known from just five specimens, collected individually between 1985 and 2024, all of them female.

“With such a small sample, chance and the opportunistic nature of the collecting are probably the simplest explanations. This does not seriously weaken our confidence that L. arawak is distinct. All five females share a consistent and unique combination of morphological characters.”
The Research Team

Type locality of *Lissomus* *arawak* in Pedernales province (el. 700 m).

The name is a deliberate tribute to the island’s first inhabitants:

“We chose the name arawak to recognise the Indigenous history and continuing cultural heritage of the Antilles. We wanted the name of this distinctive endemic species to connect the biological history of the island with its human history.”

The discovery forms part of a wider effort, they added, “to document the island’s still incompletely known insect diversity,” with at least 15 further click beetle species thought to await description in the Dominican Republic alone.

The discovery forms part of EntomoDR, a long-term field and taxonomy project documenting the still incompletely known insect diversity of the Dominican Republic through repeated expeditions and collaboration with an international network of taxonomic specialists.

Pensoft at the Nordic Oikos-GfÖ 2026 conference: Integrating the Diversity of Ecology

Between 13-17 September 2026, Pensoft Publishers joined the Nordic Oikos-GfÖ 2026 conference in Odense, Denmark.

Between 13-17 September 2026, Pensoft Publishers joined the Nordic Oikos-GfÖ 2026 conference, jointly organised by the Nordic Society Oikos and the Ecological Society of Germany, Austria and Switzerland (GfÖ) in Odense, Denmark.

Themed “Integrating the Diversity of Ecology”, the event welcomed over 1,000 researchers in the field from across career stages, who had the opportunity to enjoy conference talks across 36 thematic sessions, as many as six keynote talks, two poster sessions, several open society meetings and quite a few social events, including excursions and a conference dinner.

Conference delegates enjoying the musical clock installation mounted on an elevated balcony on the glass façade of the ODEON building, where the Nordic Oikos-GfÖ 2026 conference took place between 14 and 17 September 2026.

Throughout the scientific event, conference delegates had the opportunity to also explore the various publishing services offered by Pensoft to authors of research, journal managers, conference organisers; the diverse portfolio of almost 100 open-access peer-reviewed journals published on Pensoft’s ARPHA Publishing Platform.

Beyond publishing solutions, a key focus was given to OBSGESSION: a Horizon Europe-funded project where Pensoft is actively involved. To better understand and predict changes in terrestrial and freshwater ecosystems, the OBSGESSION consortium integrates multi-source Earth Observation data (such as high-resolution satellite imagery and drone monitoring) with ground-based in-situ research, including advanced environmental DNA (eDNA) sampling. By coupling these data streams with cutting-edge detection-attribution modelling and machine learning algorithms, the project generates scalable Essential Biodiversity Variables (EBVs). These ecological approaches and analytical frameworks are actively tested and validated through six biodiversity pilots across diverse European ecosystems. In the open-science Research Ideas and Outcomes journal, you can find a collection of project outputs, including research papers, project reports and deliverables, and guideline papers published across journals and platforms.

As a leader of the “Dissemination, Multi-stakeholder outreach and synergies” work package at OBSGESSION, Pensoft is tasked with stakeholder engagement and community building, ultimately contributing to the high impact of the resulting outputs, methodologies, and policy recommendations that aim to strengthen public understanding of biodiversity change.

Earth Observation meets in-situ biodiversity monitoring: Pensoft joins the OBSGESSION project

One of the six keynote talks was presented by Prof. Dr. Isabell Hensen (Martin Luther University Halle, Germany), who received the GfÖ Honorary Medal 2026 for her leading, forward-looking contributions to ecological research and the scientific community. Her work examines how genetic variation, environmental conditions, disturbance, and plant-animal interactions shape plant populations, with particular emphasis on rare species, biological invasions, and the regeneration of degraded forests.

In her talk, titled “One spark is enough: regeneration ecology of Andean forests under global change”, she reported on post-fire regeneration processes in tropical Andean forests, based on long-term field experiments and observational studies.

Hensen focused on the well-studied endemic plant genus Polylepis, which forms the world’s highest-elevation forests and illustrates how fire has shaped ecosystem dynamics over millennia. Her talk also mentioned a 2022 monograph of the genus, published in the Pensoft journal PhytoKeys by Tatiana Erika Boza Espinoza (Pontificia Universidad Católica del Perú) and Michael Kessler (University of Zurich), which brought together results from 35 years of field and herbarium experience.

On Wednesday, Pensoft’s Iva Boyadzhieva delivered a presentation titled “Scholarly Communication: Lessons from the Publisher’s Kitchen”. She highlighted the vital role publishers play in helping researchers communicate their insights not only to peers, but also to decision-makers and the public. Emphasizing the publisher’s responsibility to support authors with robust infrastructure and dedicated human expertise, she outlined how Pensoft works to FAIRify scholarly publishing and future-proof scientific knowledge in an era of rapid AI development and expanding research output.

Pensoft’s team was delighted to meet up with dedicated readers, authors, reviewers, and editors from across Pensoft’s portfolio, as well as introduce Pensoft journals to attendees discovering them for the first time.

Unsurprisingly, well-established society journals published by Pensoft, such as Frontiers of Biogeography, NeoBiota, Vegetation Classification and Survey, Vegetation Ecology and Diversity and Italian Botanist drew plenty of attention, alongside long-standing Pensoft’s own titles like Nature Conservation, PhytoKeys, One Ecosystem and the Biodiversity Data Journal.

Visitors were also particularly intrigued by several newly launched Pensoft journals. Developed in close collaboration with passionate researchers, these fresh outlets directly address key gaps in academic publishing.

One of the newly launched journals in the spotlight was Agricultural and Ecological Modelling (AEM), which provides a unique scholarly outlet thanks to its modern approach to publishing by increasing transparency, giving credit to research objects across the entire modelling research lifecycle. This is achieved through publishing specialised article types, such as: Formal Model, Model Testing and Calibration, Model Implementation and Documentation, Data Papers and Software Descriptions. These new publishing formats are designed to keep pace with advances in Modelling research and to make it FAIR (Findable, Accessible, Interoperable, and Reusable) by enabling scholarly credit for diverse research outputs, often created by different groups of authors. For the time being, AEM remains a Diamond Open Access journal, meaning that it will not charge authors for open-access publication.

Other recently founded journals addressing emerging and fast-developing disciplines within the ecological field that took the spotlight were:

Individual-Based Ecology: launched to support understanding and predicting ecological systems’ response to rapidly changing and novel conditions by linking individual responses to responses at higher levels of organisation.
Advances in Pollinator Research: a multidisciplinary journal publishing research on pollination ecology, pollinator-plant interactions, pollinator health and drivers of pollinator declines, crop and wild flower pollination, pollinator conservation practices, molecular ecology of pollinators, pollinator and pollination monitoring, decision support for policy and socio-economics.
Journal of Regeneration: a multidisciplinary journal for the dissemination of research results on regeneration and tissue repair across phyla. These mechanisms can be framed within an evolutionary framework and integrate a variety of cellular processes involving stem cells, dedifferentiating or even transdifferentiating cells.

All of these journals operate with no article fees for either authors, nor readers.

Supporting European Policy Through Priority Essential Biodiversity Variables (EBVs)

Delegates at the event showed strong interest in OBSGESSION’s first policy brief: “Prioritising Essential Biodiversity Variables (EBVs) to support European Union (EU) policy needs based on the EU’s Biodiversity Strategy for 2030.” To tackle a critical challenge in environmental monitoring, OBSGESSION focuses on prioritising key EBVs to directly support the EU Biodiversity Strategy 2030 – a roadmap designed to put Europe’s biodiversity on a path to recovery through 102 specific actions and sub-actions.

To align these policy needs with actionable data, the OBSGESSION team conducted an assessment to identify priority EBV candidates. By categorising EBV-applicable actions and indicators across different ecosystem realms and implementation stages, the project pinpointed the most essential variables needed to strengthen monitoring, reporting, and policy execution. The document is based on a deliverable by the project (D1.1 Policy Landscape and Needs Assessment).

This policy brief is part of a broader, ongoing effort within OBSGESSION to bridge the gap between biodiversity data and policy execution. To dive deeper into the science behind this topic, the project has hosted a dedicated seminar series exploring key aspects of the framework:

Policy Landscape & Needs: [Watch seminar]
EBV Fundamentals: [Watch seminar]
EBV-Enabling Products: [Watch seminar]

Bringing Methodologies to Life Across European Ecosystems

Beyond theoretical frameworks, OBSGESSION grounds its research in six biodiversity validation pilots across Europe. The case studies represent European biodiversity and ecosystem conservation challenges at scales varying from local to regional. Full details on each ecosystem pilot are now available in a collection of newly published pilot factsheets, which made their debut at the conference, where people could take a look at their digital versions.

Reading those materials gives an insight into the practical testing environment to demonstrate how Earth observation, field research, and ecological modelling come together to deliver actionable biodiversity insights. You can also check out OBSGESSION’s biodiversity pilots on the project’s website.

The OBSGESSION in a Nutshell video presents a concise overview of the project’s overarching mission and components.

Vivid orange killifish discovered in the Brazilian Amazon

Researchers have described a new species of brilliantly coloured fish from a network of forest streams in the Brazilian Amazon, and have already recommended it for listing as Endangered because of the pressures facing its only known home.

The fish, named Laimosemion laranja, is a killifish measuring less than three centimeters in standard length. Males are strikingly patterned, with rows of orange spots along the front half of the body and bold, chevron-shaped orange bars towards the tail, set against a pale grey flank.

It was found by Brazilian researchers from the Universidade Federal do Rio Grande do Norte, the Instituto Peixe das Nuvens, the Universidade Federal do Pará and University of West Florida, during fieldwork in the Rio Cajari drainage in the southern state of Amapá.

“We are developing a research project aimed at investigating the evolution of life-history strategies in freshwater fishes of the family Rivulidae across different biomes in Brazil.

During our sampling in small rivers locally known as ‘igarapés’ in the Rio Cajari region, in Amapá State, we found this fish with a very striking coloration, which immediately caught our attention.”

Confirming that the fish was new to science required close comparison of its body proportions, scale counts and skeletal features against its closest relatives, together with an analysis of its mitochondrial DNA.

“It was an unexpected moment. Initially, what most caught our attention was the impressive coloration of the males and females, which was unlike anything we had previously encountered in the study area. This sparked our admiration and a great deal of curiosity.”
Yuri Abrantes

Once the genetic analysis confirmed the fish’s distinct identity, he said:

“It was something special, as we saw an opportunity to contribute to increasing our knowledge of Amazonian biodiversity and to draw attention to the conservation of areas that are still poorly explored but highly threatened.”

The species’ name, laranja, is Portuguese for both the colour orange and the fruit, a fitting nod to the males’ vivid markings. It also honours Laranjal do Jari, the Amapá municipality where the fish was found.

“We wanted to choose a name that would highlight a characteristic of the fish while also fostering a sense of connection with the people of the region where it was discovered.”
Yuri Abrantes

Laimosemion laranja belongs to a group of Amazonian killifish, some of which have evolved an unusual survival strategy: their embryos can pause development entirely, lying dormant in damp mud until seasonal pools refill with rain.

“Laimosemion represents one of the five independent origins of the annual life cycle within the family Rivulidae.

Laimosemion laranja is particularly interesting because it expands our knowledge of the diversity and evolution of this group in the region.”
Yuri Abrantes

The new species is currently known from just three small forest pools near Laranjal do Jari, all showing signs of disturbance from deforestation, mining and urban expansion; one site lies close to water discolored by mining sediment, while another, within the city itself, is affected by plastic pollution.

With its entire known range covering an estimated 25 square kilometers, the researchers argue that Laimosemion laranja meets the criteria for an Endangered listing under IUCN guidelines, and have recommended extending the boundaries of the neighboring Rio Cajari Extractive Reserve to help protect it.

The study is published in the open-access journal Zoosystematics and Evolution.

Sixteen new fungus species found hiding in Thailand’s flowers

Researchers have discovered sixteen new species of fungus living unnoticed inside garden and wild flowers across northern Thailand, more than quintupling the number of such fungi known to occur in the country.

Researchers have discovered sixteen new species of fungus living unnoticed inside garden and wild flowers across northern Thailand, more than quintupling the number of such fungi known to occur in the country.

The fungi belong to Aureobasidium, a genus of dark, yeast-like organisms found almost everywhere on Earth, from human skin to glacial ice. Several members of the group are already prized in industry for producing useful enzymes, fighting plant disease and even breaking down plastic. Yet despite their familiarity, little was known about the diversity within Thailand’s tropical flowers.

Researchers from Chiang Mai University and Kasetsart University collected 54 fungal strains from 31 species of flower during a 2024 survey, among them bougainvillea, butter daisy, and periwinkle. Using a combination of DNA analysis across five gene regions, microscopy and growth trials, the team distinguished sixteen entirely new species, alongside five already known species (four of which had never before been recorded in Thailand).

Professor Nakarin Suwannarach of Chiang Mai University.

“Our team was motivated to study Aureobasidium because it was one of the most frequently isolated fungal genera from our flower samples.

We observed considerable variation among the isolates in colony morphology and other phenotypic characteristics, which suggested that there might be much greater species diversity than previously recognised.”

Distinguishing the new species was far from straightforward. Many looked almost identical under the microscope, and the DNA markers usually relied upon proved unable to tell them apart.

“This highlighted the limitations of relying on morphology alone, as well as on commonly used molecular markers.

By integrating multiple loci with morphological, physiological and growth-temperature data, we were able to distinguish closely related species more accurately. This was particularly surprising because Aureobasidium is a well-known fungal genus, yet our results revealed substantial previously unrecognised diversity in Thailand.”
Professor Suwannarach

Most of the new species take their names from the flowers in which they were found, including Aureobasidium bougainvilleae, A. catharanthi and A. plumeriae, while others honour the northern Thai locations where they were collected.

Two species, A. saisamorniae and A. savitreeae, were named in tribute to two of Thailand’s leading mycologists, Professor Saisamorn Lumyong and Professor Savitree Limtong.

“We wanted the names to tell a story, either about where these fungi came from or about the people who have helped advance mycological research in Thailand.”
Professor Suwannarach

Beyond the taxonomy, the team says the findings matter for the future. A small number of Aureobasidium species have been linked to opportunistic infections, so having an accurate record of which species occur naturally will help scientists spot and respond to any change in their behaviour over time.

“This study demonstrates that multilocus phylogenetic analysis is not simply a tool for naming new species. It can reveal hidden fungal diversity and provide essential baseline information for understanding and monitoring fungal populations in the future.”
Professor Suwannarach

The study is published in the open access journal IMA Fungus.

New species of egg-eating snake described from Harenna Forest in Ethiopia

A new species of snake that feeds exclusively on birds’ eggs has been described from the Harenna Forest in Ethiopia, one of the last substantial tracts of natural forest left in the Horn of Africa.

Named Dasypeltis albigularis, or the ‘White-throated Egg-eater’, the species belongs to a remarkable group of harmless African snakes that survive entirely on a diet of eggs, using specially adapted vertebrae in the throat to crack the shell before swallowing.

Male *Dasypeltis* *albigularis* sp. nov. from Manyate village, Harenna Forest, Ethiopia. Image credit: Arthur Tiutenko et al., 2026.

It joins around 20 other known species in the genus Dasypeltis, most of which are notoriously difficult to tell apart, since many are uniformly black, brown or grey with few obvious external differences.

The research, published in the open-access journal Herpetozoa, was led by Arthur Tiutenko of Friedrich-Alexander-Universität Erlangen-Nürnberg, together with colleagues at Ludwig-Maximilians-Universität Munich and South Africa’s National Museum in Bloemfontein.

The new species is superficially similar to the so-called Montane Egg-eater, Dasypeltis atra, a black-coloured snake found in forests across East Africa, but genetic analysis of both mitochondrial and nuclear DNA showed the two are as distinct from one another.

The investigation began when Dr Tiutenko acquired a juvenile female snake from a local collaborator in the Harenna Forest:

“I received a juvenile female of an egg-eater that appeared to me to be an already known species, and I started looking for a male to breed it. As she grew to adult size, I noticed morphological differences.”

To test whether those differences reflected a genuine biological distinction, Dr Tiutenko paired the female with a male of the closely related species she resembled:

“I crossed them nevertheless, to see how the offspring would turn out and how her characteristics would be inherited.”

Dasypeltis albigularis sp. nov. Image credit: Arthur Tiutenko et al., 2026.

The resulting hybrid offspring displayed a mix of traits from both parents, providing early evidence that the Harenna Forest snake was something new. Confirming the discovery with a formal description ultimately took seven years, drawing on morphological comparisons, DNA sequencing and captive breeding observations.

Dasypeltis albigularis can be distinguished from its relatives by the pale, sometimes bluish-tinged skin visible between its scales and a distinctive white throat and belly – a feature reflected in its scientific name, which means “white-throated” in Latin.

Unlike some of its relatives, it also appears to lack the ability to produce the rasping, hissing sound that many egg-eating snakes use to fend off predators by rubbing their scales together. Females of the new species reach up to 92 cm in length, somewhat smaller than D. atra and its other closest relatives.

The snake lives in dense forest between 1,500 and 1,700 metres above sea level, in an area whose undergrowth includes wild coffee plants, and feeds on the eggs of tree-nesting birds.

The description of Dasypeltis albigularis adds to a long list of species Dr Tiutenko has helped bring to scientific attention:

“This is my twentieth taxon that I have named and described. I now have five or six species, and one subgenus, in the queue.”

Until next time

The 4th BioSyst.EU meeting took place in Uppsala, Sweden, from 17 to 19 August 2026, organised by the Swedish Systematics Association, in collaboration with Uppsala University. For three days, the conference brought together European systematists to celebrate the discipline in the very city where it was born, home to Carl Linnaeus and the foundations of modern taxonomy.

BioSyst.EU exists to give individual scientists across Europe a shared platform, working through their national and regional societies rather than institutions. It sits alongside the Consortium of European Taxonomic Facilities (CETAF), which represents natural history institutions, and together the two bodies aim to strengthen systematic biology, phylogenetics and biodiversity research across the continent.

This year’s programme combined talks, workshops and symposia with visits to historical sites connected to Linnaeus. The main event was preceded by an early career meeting on Sunday 16 August, which gave students and early career researchers a chance to connect before the conference proper began.

Meeting the community at our booth

Pensoft were delighted to attend with our own booth, where colleagues came to chat about our publishing services, from manuscript to final publication, as well as our tools for managing and publishing taxonomic and biodiversity data.

It was a great opportunity to introduce our journal portfolio – more than half of which comprises taxonomy and systematics titles – to old friends and new faces alike, including titles such as:

ZooKeys – one of the world’s leading journals for zoological taxonomy and biodiversity research, publishing new species descriptions and revisions across the animal kingdom
MycoKeys – dedicated to fungal systematics, taxonomy and biodiversity, supporting mycologists with rapid, richly illustrated publishing
PhytoKeys – focused on plant systematics and biodiversity, covering everything from single species descriptions to large-scale floristic studies
Metabarcoding and Metagenomics (MBMG) – a journal built around the fast-growing field of DNA-based biodiversity assessment, from environmental DNA to large-scale metagenomic surveys
Zoosystematics and Evolution – published with the Museum für Naturkunde Berlin, covering zoological systematics, morphology and evolutionary biology
Evolutionary Systematics – dedicated to whole-organism biology of extant and fossil animals

…and many more!

Conference presentation highlights

One of the undoubted highlights of the conference was the keynote talk by Sandra Knapp, editor-in-chief of PhytoKeys, titled Taming the beasts: strategies for studying megadiversity. Knapp tackled the question: what do we do with genera that contain more than a thousand species?

She subsequently made the case that studying genera properly, from geography to identification, pays dividends for both collaborative science and our understanding of evolution.

Another highlight was the keynote lecture by Paul Hebert, Chair of the MBMG Advisory Board: The End Game – All Species & Their Interactions. Hebert reflected on the tens of millions of multicellular species we share the planet with, most still undescribed and many at risk of disappearing before they are even documented.

Among the other talks we attended was by one of our long-time partners, Olaf Banki, on the Catalogue of Life: taxonomic data services and infrastructure for all. Olaf reflected on the initiative’s evolution, from its origins thirty years ago to today, where the Catalogue of Life now serves as the taxonomic reference underpinning close to 4 billion species occurrences mediated through GBIF.

He gave a valuable overview of where the initiative stands: what it offers different user groups, including taxonomists and data infrastructures, where taxonomic data gaps remain, and how the community can contribute going forward.

Notably, Pensoft’s journals are integrated with Catalogue of Life to help list the species of the world. You can find out more about this initiative by accessing the following blog post.

A final highlight was Alexander Edwards’ presentation, titled Where Were You Yesterday? Interrogating Floral Constancy in Bumble Bee Workers Using Pollen Metabarcoding. Edwards presented work using ITS2 pollen metabarcoding to study the foraging behaviour of individually marked Bombus terrestris workers in a semi-natural university garden, sampling pollen non-lethally from returning foragers over several days.

It was particularly nice to catch up with Alexander, having worked with him previously on a guest blog post, The bee’s knees: a new, non-lethal way to study pollinator networks, which explored the same non-lethal sampling approach.

An excursion to Linnaeus’ Hammarby

On 20 August, participants also had the option to join an excursion to Hammarby, Linnaeus’ summer house just outside Uppsala. It is a rare chance to step inside an authentic 18th century Swedish manor that reveals both the private life of Linnaeus and the scientific work he carried out there!

Pensoft notably visited the University of Uppsala Botanical Garden, also known as the Linnaean Garden, where Olof Rudbeck the Elder and Carl von Linnaeus worked:

Until next time

The 4th BioSyst.EU meeting was a fitting tribute to the roots of systematics, held in the city where the discipline effectively began. From megadiverse genera to pollen metabarcoding and the future of biodiversity monitoring, the talks reflected how dynamic the field remains. We were delighted to be part of it, and to spend three days connecting with the scientific community. We look forward to the next BioSyst.EU meeting!

New spider species discovered in Idaho, named in honour of the University of Idaho’s “Vandals”

Researchers at the University of Idaho have identified a new species of spider in the mountains of northern Idaho and given it a name that pays tribute to the university itself: Hexura vandal.

Researchers at the University of Idaho have identified a new species of spider in the mountains of northern Idaho and given it a name that pays tribute to the university itself: Hexura vandal.

The spider belongs to a small group of funnel-web spiders related to tarantulas. Until now, only two species in this genus were known, both living hundreds of miles away in the coastal forests and mountains of Oregon and Washington.

Finding a third species so far inland, in the Rocky Mountains near the town of Kooskia, came as a surprise to the research team, led by Arnau Calatayud-Mascarell, Ethan J. Briggs and Chris A. Hamilton. It extends the known range of the genus by roughly 500 kilometres and is the first new taxonomic work done on this group of spiders in almost fifty years.

Associate Professor Dr. Chris A. Hamilton stated:

“It’s always exciting when you realize the samples you’ve been looking at are an undescribed new species. This is one of the main reasons we do this job – to document Earth’s incredible biodiversity and expand our foundational biological knowledge of our planet. It just makes it even more exciting when that undescribed diversity can be found in your backyard (figuratively speaking).”

The name is where the story becomes especially local. Rather than a Latin descriptor, the researchers chose “vandal”, which is a direct nod to the university’s own mascot. The nickname dates back to 1917, when student journalist Harry Lloyd McCarty described the men’s basketball team’s fierce style of play as “vandalizing” their opponents. The name stuck, and the University of Idaho remains the only Division I university in the United States with the Vandals as its mascot.

When discussing how the name was picked, Hamilton said:

“It didn’t take very long for the lab to sit down and decide what to name the new species. It was basically, this is really unique because it’s only found in Idaho and it’s not very far (relative) from campus. It’s black (sorry that it’s not black and gold like the school colors!). It’s a predator that attacks. It’s a Vandal.”

The discovery comes with a note of caution. Hexura vandal has so far only been found in a handful of sites within a very small area of forest in Idaho, despite repeated searches nearby. The region faces pressure from logging, and wildfires, which are becoming more frequent, and tend to strike during the spiders’ breeding season. Taken together, these factors have led the researchers to consider the micro-endemic species likely endangered, and they hope the discovery will help build the case for protecting its habitat.

The findings are described in a newly published scientific paper in ZooKeys by the research team, based at the University of Idaho’s Department of Entomology, Plant Pathology and Nematology.

University of Idaho, home of the Vandals, is Idaho’s land-grant university and the state’s first Carnegie R1 research institution — a ranking reserved for the top 4% of U.S. universities. From its residential campus in Moscow, U of I serves the state through centers in Boise, Coeur d’Alene, Idaho Falls and McCall, nine research and Extension centers, and Extension offices in 42 counties. With more than 12,000 students, U of I is a leader in student-centered experiential learning, interdisciplinary research, business and community service and global outreach. The Vandals compete as a founding member of the Big Sky Conference and as an affiliate in the Big West and Mountain Pacific Sports Federation.

A Coral Among the Stars: New Species Discovered on Costa Rica’s Deep-Sea Seamounts

The coral was found thriving in large numbers on rocky outcrops that were almost entirely blanketed by brittle stars.

Scientists exploring seamounts off the coast of Costa Rica have discovered a new coral so genetically and morphologically distinct that it required the creation of an entirely new family for its classification.

Bright yellow and tree-like, the coral was found growing some 360 to 529 metres beneath the surface of the Pacific. The discovery is described in the open-access journal ZooKeys.

The colonies, which can grow to over a metre tall, were collected using the remotely operated vehicle SuBastian aboard the research vessels Falkor and Falkor (too), operated by the Schmidt Ocean Institute, during expeditions to the seamounts off Isla del Coco and the Costa Rican Pacific margin in 2019 and 2023.

Researchers found the coral thriving in large numbers on rocky outcrops that were almost entirely blanketed by brittle stars, creating a shimmering, star-strewn seafloor from which the golden coral branches rose like glowing trees.

That image inspired the coral’s name. The new genus, Laurinque, comes from “Laurinquë”, meaning “golden tree” in Quenya, the Elvish language devised by J.R.R. Tolkien for The Lord of the Rings and The Silmarillion, chosen in reference to the colonies’ bright yellow, tree-like form.

The species name, elenya, is Quenya for “stellar” or “of the stars”, a nod to the fields of brittle stars among which the coral was discovered. Together, the pairing evokes a scene the researchers likened to a mystical elvish landscape on the deep seafloor.

Working out where this coral belonged in the coral family tree proved unusually difficult. The team sequenced three genes commonly used to classify corals, and each one pointed to a different, unrelated family, an unusually high level of disagreement.

To settle the question, researchers turned to phylogenomics, analysing hundreds of genes at once. This revealed that the coral does not belong to any known family at all, but represents a unique evolutionary lineage most closely related to the family Eunicellidae, but distinct enough in both its genetics and its anatomy to warrant a new family, Laurinqueidae, and a new genus, Laurinque, built specifically to house it.

“I saw the octocoral garden for the first time in 2019 and I was impressed by the beauty of the landscape, which inspired, later the elvish name of the taxa. I thought the species could belong to a known family and genera, but after the preliminar morphological analysis I realised that it was something very different that I could not match with the known taxa.

In 2023 we collected more samples and thanks to the exhaustive molecular analyses made by my colleagues, Cathy McFadden, Catalina Murillo and Andrea Quattrini, we were able to determine the taxonomic placement of the stunning species, in one of the most enigmatic sites.”
Dr Odalisca Breedy of the Universidad de Costa Rica

The research was led by Dr Breedy, working alongside an international team of collaborators. The expeditions were supported by the Schmidt Ocean Institute and a National Geographic Society research grant.

The discovery adds to a growing list of undocumented species being revealed on Costa Rica’s seamounts, and demonstrates how much of the deep ocean, which covers roughly two-thirds of the planet’s surface, remains unexplored.

Coral gardens such as these are considered vulnerable marine ecosystems, providing structurally complex habitat for a wide range of other deep-sea life.

New Mountain Dragon Lizard From Thailand Named After Syrax From House Of The Dragon

Meet Acanthosaura syrax, the mountain horned dragon lizard named after Syrax – Queen Rhaenyra Targaryen’s dragon in House of the Dragon.

Scientists have described a new species of lizard from the high mountain forests of western Thailand, and have given it a name straight out of fantasy television: Acanthosaura syrax, named after Syrax, the dragon ridden by Queen Rhaenyra Targaryen in House of the Dragon.

The lizard belongs to a group known as mountain horned dragons, agamid lizards recognised by the spiny crests running along their neck and back. It was discovered in the evergreen forests of Mae Wong National Park, in the Tak-Kamphaeng Phet Province, at elevations above 1,300 metres, where it appears to live nowhere else. The find brings the total number of known species in the genus Acanthosaura to 23.

The research team, led by Poramad Trivalairat and colleagues from Chulabhorn Royal Academy and Kasetsart University, chose the name Syrax deliberately. The dragon of that name in the fantasy world is known for its striking yellow colouring, its comparatively modest size next to other dragons, and for producing an unusually large number of eggs.

The researchers found all three qualities echoed in the real animal: A. syrax has yellowish-green tones in its colouring, is one of the smallest members of its genus, and lays notably large clutches of eggs for its size. The team has proposed “Syrax mountain horned dragon” as its English common name, alongside a Thai name that translates the same way.

Beyond the name, the lizard stands out for possessing the smallest neck and back crest scales recorded anywhere in the genus, along with an overall small body size. It also lacks a black patch around the eye seen in several related species, and has a distinctive dark collar marking. DNA analysis of two genes backed up what the researchers saw by eye, showing that A. syrax is genetically distinct from its closest relative, A. lepidogaster, and from every other known species in the group.

The species appears to be confined to a narrow band of high-altitude forest, and the researchers say its populations are naturally scattered by the rugged terrain of the mountain range, a state of affairs that leaves it vulnerable should its habitat come under further pressure. They are calling for stronger protection of Mae Wong’s high-elevation forests, suggesting the new lizard could serve as a flagship species for the area alongside other rare wildlife found there, including the Asian forest tortoise, Oldham’s leaf turtle and the Indochinese tiger.

The study is published in the open-access journal ZooKeys.
